Beit known that I, GEoRGEEg-PALMER, of Elmira, in the county of Chemung,in the State of New York, have inventedy new and useful Im rovements inStove-Rings, of which the fo lowing, taken in connection with theaccompanying drawings, is a full,

clear, and exact descriptlon.

This invention relates to` certain improve# ments in stove rings forreceiving and supporting cooking utensils some distance above thesurface of the'stove to prevent burning of the cooki material.

My main o ject is to provide a stove ring I for the purpose describedand which is comparati-vely light and may be manufactured at a minimumcost and at the same time afford Ventilating means for the' escape ofthe heated air fromv within the ring when the cooking utensil is mountedthereon. In other words, this object more specifically stated is to makethe body of the r1 from a single piece of light sheet metal inw 'ch thevent openings are stamped or pressed therein and to reinforce thelongitudinal edges of .the by wires over which portions of the sheetmetal band are bent and to provide the meeting ends'of the sheet metalbody with integral parts adapted to be bent or clenched 1ntointerlocking engagement with each other. y

In the drawings-Figure 1 is a face view partly in section and partlybroken away of the extending band and reinforcing rods for forming thering Fig. 2 is a pers ective view of the completed stove ring. Fi) 3 isan elevation of the same showing a ettle mounted thereon. F' 4 is anenlarged face view of the meeting ends of the ring showing theinterlocking members in operative position.- Fig. 5 is a sectional vietaken on line 5-5, Fig. 4. e f

As shown in the drawings this stove ring consists essentially of astrip1.1 of comparatively light lsheet metal site longitudlnal edges orrods provided with over turned lengthwise ilanges -2- inclosingsuitablereinforcing wires -3- which latter may, however, be omitted ifdesired and the over turned ed es v.-2#- relied upon to sufficientlystiffen t e sheet metal strip -1-.

The intermediate portion of this strip -1-,- is formed at intervals witha series of diamond-shaped perforations 4 formin vent openings to permitthe escape of heate aving its oppoair from within the ring when it isresting on the stove .with a kettle or other cooking utensil as .5mounted thereon as best shown inFig. 3.

One endof the strip -1- is formed with an integral tapered ton e -6-while theolpposite end is forme with a transverse s ot --7-- ofsubstantially the same dimensions as the transverse dimensions of thetongue -6- which it is adapted to receive when the ends are broughttogether as shown in Figs, 2, 3, 4 and 5;

-The end of the sheet metal stripl -1- which is formed with a slot -7-is proing a central lengthwise slit or slot -9- extending inwardly fromits extremity for the purpose of forming opposite locking members -10-adapted to be folded on diagonal lines .-11 and against the sides il);one of the openings -4 as best seen in When thestrip is bent in circularform as shown in Fig. 2, the extension 8 is lap ed u on the outer faceof the opposite en of t e strip between the flanges 2 -whereupon thetongue -6- is bent laterally and inserted through the transverse slot 7and clenched upon the outer face of the extension -8- and at the sametime the interlocking members -10- at opposite sides of the slit 9 arebent through the adjacent opening -4 and clenched upon I'the inside ofthe strip 1 thereby affording a double lock for the meeting ends of thering'. It is now apparent that the opposite ends of the strip arereduced to somewhat less width than the main body of the strip formingshoulders -12- at the'base of the tongue -6- and additional shouldersl3- at the b ase of the reduced extension -8-, said shouldersformingabutments which are brought together and determine thecircumference of the ring as clearly' seen in Figs. 2 and 3.

The slot 7- is disposed in substantially the sametransverse line as theshoulders -13- While the sides of the opening -4- nearest the base ofthe tongue -6- are disposed a distance from the base of said tonguesubstantially equal to the distance between the slot -7- and diagonallinesu ing members -10- will be brought into registration respectivelyAwith the transverse slot -7- and adjacent sides'of the opening -4-nearest the tongue (5- whereupon said tongue 6- may be readily vinsertedthrough the slot -7 and clenched u on the outer face of the extension-8- an at the same time the locking members -10- are folded upon thelines 1lthrough the adjacent opening l1- and clenched upon the innerside of the stri thereby firmly locking the meeting ends o the bandtogether and forming a practically rigid annulus or ring capable ofsupporting ordinar cooking utensils.

hat I claim is:

1. A stove ring comprising a sheet' metal strip havin its oppositelongitudinal edges over turne towar each other and inclosing lengthwisereinforcing wires, the intermediate portion of the strip being formedwith vent openings, one end. of said strip being reduced in Widthandprovided with a central lengthwise slit opemng from its eX- tremityand provided with o posed bendable locking members adapte to enter oneof the vent openings in the opposite end of 1 the strip and to beclenched upon the sides of said opening.

2. A stove ring comprising a sheet metal strip bent into circular formand havin its opposite longitudinal edges over turne toward each otherforming lengthwise reinforcing flanges, the main body lbeing formed withvent openin s, reinforcing rods embraced Within sai flanges, one end ofthe strip being providedwith a tongue and the opposite end being formedwith a groove, the tongue being inserted through the groove and clenchedupon the adjacent portions of the strip, the end of the strip oifset tothat which is .provided with a tongue having a reduced extension formedwith a lengthwise slit opening from its extremity forming opposedbendable locking members adapted to be inserted through and clenchedupon the sides of one of the vent openings.

In witness whereof I have hereunto set my hand this 13th day of July1907.
